A 27-year-old Casselberry man is accused of killing a Texaco gas station clerk in Casselberry and committing eight robberies throughout Seminole County, police announced Tuesday.

The suspect, Mack Jackson, is accused of fatally shooting Omar A. Raheem, 31, on Sunday. Jackson is being held at Seminole County jail without bond.

Raheem was killed after being shot during a robbery Sunday night at the Texaco shop he co-owns with his uncle Nezar Saeed Hammo. Another employee, Clifford Hipp, was in the store at the time of the robbery but was not physically injured, Casselberry Police Sgt. Bill Nas said.

Nas said the suspect asked to buy two cigars from Raheem, and as the clerk opened the cash register to complete the transaction, the suspect demanded cash and shot Raheem.

The gun then malfunctioned, and the suspect fiddled with the gun and called Hipp to come behind the register, Nas said.

The suspect fled on foot after taking less than $1,000 from the store, Nas said.

The Seminole County Sheriff's Office and the Altamonte Springs, Casselberry and Sanford Police Departments met Monday to compare evidence in recent unsolved robbery cases, and two tips to a police hotline later that afternoon identified Jackson as a possible suspect, according to a police statement.

A fingerprint on a video game found at the GameStop in Casselberry that was robbed Tuesday matched Jackson's, Nas said. When Casselberry police brought Jackson in to question him, he confessed to robbing a total of eight Seminole County stores, including the Casselberry GameStop and Texaco.

Nas said Jackson admitted to shooting Raheem but said the gun went off by accident. Jackson told police he did not mean to shoot Raheem.

Jackson also is accused of robbing the Winn-Dixie liquor store in Fern Park at about 8 p.m. Sunday, directly before the robbery at the Casselberry Texaco, said Seminole County Sheriff's Office spokeswoman Kim Cannaday.

He is accused of taking $200 and a couple bottles of alcohol from the store with threat of a handgun.

Cannaday said Jackson also is accused of robbing Erotic Emporium in Longwood around 1:30 p.m. on June 18. Jackson is charged with taking $308 with threat of a handgun.

Jackson was arrested Monday night at a hotel in Altamonte Springs, police said.
